PAUL L. WOSS, OF CHICAGO, ILLINOIS.

VENEER-GLUING PRESS.

Application filed July 1, 1915.

To all whom z't'mag concern:

Be it known that 1, PAUL L. Woss, a citizen of the United States, and aresident of the city of Chicago, county of Cook, and State of Illinois,have invented certain new and useful Improvements in Veneer-GluingPresses, of which the following is a specification.

My invention relates to improvements in veneer gluing presses, and hasfor its object the production of a device of this character whichwill beof durable and economical construction and efficient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a perspective view of a veneer gluing press embodying theinvention, Fig. 2 is a partially sectional side elevation of the press,Fig. 3 is an elevation of one end of the clamping device of the press,with a plate removed to expose underlying parts and portions shown insection, Fig. 4 is an elevation of the opposite end of the clampingdevice, Fig. 5 is an enlarged section taken on substantially line mw ofFi 4, Fig. 6 is a fragmentary perspective view of one of the clampingjaws included in the invention, and Fig. 7 is a detail section taken onsubstantially line y of Fig. 5.

The preferred form of construction, as illustrated in the drawings,comprises a bed or table 1 which is supported upon legs 2. Arranged inopposite parallel edges of the bed 1 are channel guides or rails 3 whichare rigidly secured in position.

Cooperating with the bed 1 is a clamping d'vice consisting of a carriagewhich comprises end members 4 and 5 which are positioned .at theopposite edges of said bed, and which are rigidly connected by aconnecting member 6 which extends under the bed, as clearly shown inFig. 5. Provided upon the inner sides of end members 4 and 5 are rollers7 which engage in the channels 3 to loosely support the carriage, it

being clear that with this arrangement, the

carriage and hence the clamping deviceis free for adjustment along thebed to any position desired.

Cooperating with the upper side of the bed 1 is a plurality of clampingarms 8 each of which comprises an elongated body 9 which is hinged atone end as at 10, to the end member 4 of the carriage.

Cooperating with each clamping arm is a leaf spring 11 which serves tonormally hold the free end of the former .in elevated or inoperativeposition, one end of said spring being secured to the end member 4, theopposite end thereof pressing against the under side of the adjacent:downwardly projecting end of the body 9. Also co operating with eachclamping arm is a counter-balance weight 12 the purpose of which is toassist the spring 11 in normally holding the clamping arm in inoperativeposition. Each .weight 12 is connected with the corresponding clampingarm by means of a shank 13 which is fastened to the rearward end of thearm by means of a thumb nut 14 and a cooperating threaded stud 15, saidstud projecting upwardly from the clamping arm through an elongated slot16 formed in the shank, as clearly shown in Figs. 1 and 5. With theconstruction set forth, it will be seen that the counter-balance weightmembers are connected with the clamping arms in such a manner as topermit of adjustment so as to secure the desired balancing effect uponthe clamping arms.

The clamping arm bodies 9 are locked in lowered or operative position bymeans of pawls 17 pivoted at 18 in the end member 5, said pawls beingadapted for engagement with depending loops or staples 19 provided atthe outerends of the members 9,

'as clearly shown in Fig. 3. A leaf spring 20 cooperates with eachpawl17 for normally holding the same in operative pos1- tion, thearrangement being such that upon I lowering of any arm member 9 tooperative position, the same will be automatically locked in thisposition through engagement of the corresponding pawl 17 with thecorresponding loop or'staple 19. The pawls 17 are simultaneously rockedto releasing position by means of an exteriorly projecting in said plate.

handle 21 which is fulerumed at 22 in the end member 5. The inner end ofarm 21 1s adapted to engage w1th one arm of a bell crank lever 23 whichis pivoted at 21 in member 5, the other arm of said bell crank leverengaging with a plate 25 which is shiftably mounted upon headed pins 26which engage with elongated slots 27 formed In the upper edge of plate25 are formed shoulders 28 which are adapted for engagement with thelower ends of pawls 17, the arrangement being such that, upon shiftingof the plate 25 to the right, as shown in Fig. 3, said pawls will berocked to releasing position. The handle 21 is operatively connectedwith the plate 25 through the medium of the bell crank lever 23 so thatupon dowi'iward rocking of the outer end of said handle, said plate 25will be shifted as mentioned to effect rocking of the pawls 17 toreleasing position. Hence with this arrangement, unlocking of theclamping arm is effected by simply depressing the outer end of handle21. Upon release of said handle, the springs 20 acting through themedium of pawls 17, will shift the plate 25 back to its initialposition, as

.shown in Fig. 3.

slidably engage openings 31 formed in the corresponding member 9. Theopenings 31 are reinforced, as seen, with metallic bushlngs. 1th thisarrangement the aws 29 will be locked against longitudinal or horizontalmovement but permitted free transverse or vertical movement. The underside of each aw is inclosed in a reinforcing protecting channel 32formed of sheet metal which is secured in position by bolts andcooperating nuts 33.

Provided upon the upper end of each jaw 29 is an elongated plate 3-1,the correspond ing arm member 9 being slotted as at 35 to affordclearance for said plate. Each of the plates 31 is shiftably secured tothe corresponding jaw by means of angular keepers 36 which engage withlaterally projecting flanges 37 provided at the lower edge. of saidplate, as clearly shown in Fig.

'6. Formed in each of the plates 3 1 is a pair of inclined cam slots 38which are engaged by transversely extending pins 39 secured to thecorresponding arm body 9. Vith this arrangement, it will be seen thatvertical movement of any one of the clamping aws 29 may be effected bysimply shifting the cam plate 3.4-. cooperating therewith. it beingclear that upon shifting of said plate, the

pins 39 will engage with the longitudinal edges of the slots 38cooperating w1th said jaw and thus effect raising or lowering of thejaw, depending upon the direction in which the plate is moved. Shiftingof each plate 3+1 is effected by means of a lever 10 which is fulcrumedat ll to each of the arm members 9, the lower end of said lever beingprovided with an elongated slot 42 which engages with a laterallyprojecting pin 1-3 provided upon the corresponding plate 31. With thisarrangement, it will be seen that shifting of any one of the plates 34:may be effected by simply tilting the corresponding lever 40.

In using the press, the veneer and the work to which the same is to beapplied are arranged upon the bed 1. After the veneer has been placed asdesired upon the work, the clamping arms 8 .are rocked downwardly tooperative position, the same being automatically locked in this positionby means of the pawls 17 as above described. When this is done, theclamping jaws 29 are pressed into secure engagement with the veneerthrough tilting of the levers 10, said jaws being locked in clampingposition through frictional engagement of the plates 3-lwith the pins39. In releasing the clamp ing arms, the levers A0 are first rocked toraise the jaws 29, whereupon the handle 21 is depressed to unlock theouter ends of said arms. This having been done, the springs 11 andcounter-balance weights 12 serve to automatically rock the clamping armsupwardly to inoperative position.
